## Summary
This PR simplifies the virtual file support in the red knot core,
specifically:
* Update `File::add_virtual_file` method to `File::virtual_file` which
will always create a new virtual file and override the existing entry in
the lookup table
* Add `VirtualFile` which is a wrapper around `File` and provides
methods to increment the file revision / close the virtual file
* Add a new `File::try_virtual_file` to lookup the `VirtualFile` from
`Files`
* Add `File::sync_virtual_path` which takes in the `SystemVirtualPath`,
looks up the `VirtualFile` for it and calls the `sync` method to
increment the file revision
* Removes the `virtual_path_metadata` method on `System` trait
## Test Plan
- [x] Make sure the existing red knot tests pass
- [x] Updated code works well with the LSP
## Summary
This PR adds support for `textDocument/didChange` notification.
There seems to be a bug (probably in Salsa) where it panics with:
```
2024-08-22 15:33:38.802 [info] panicked at /Users/dhruv/.cargo/git/checkouts/salsa-61760caba2b17ca5/f608ff8/src/tracked_struct.rs:377:9:
two concurrent writers to Id(4800), should not be possible
```
## Test Plan

## Summary
This PR adds basic support for files outside of any workspace in the red
knot server.
This also limits the red knot server to only work in a single workspace.
The server will not start if there are multiple workspaces.
## Test Plan
https://github.com/user-attachments/assets/de601387-0ad5-433c-9d2c-7b6ae5137654
## Summary
This PR adds the `bytes` type to red-knot:
- Added the `bytes` type
- Added support for bytes literals
- Support for the `+` operator
Improves on #12701
Big TODO on supporting and normalizing r-prefixed bytestrings
(`rb"hello\n"`)
## Test Plan
Added a test for a bytes literals, concatenation, and corner values
The `SemanticIndexBuilder` was causing a cycle in a salsa query by
attempting to resolve the target before the value in a named expression
(e.g. `x := x+1`). This PR swaps the order, avoiding a panic.
Closes#13012.
## Summary
This PR removes notebook sync support from server capabilities because
it isn't tested, it'll be added back once we actually add full support
for notebook.
## Summary
When following the step-by-step instructions to run the benchmarks in
`CONTRIBUTING.md`, I encountered two errors:
**Error 1:**
`bash: hyperfine: command not found`
**Solution**: I updated the instructions to include the step of
installing the benchmark tool.
**Error 2:**
```shell
$ ./target/release/ruff ./crates/ruff_linter/resources/test/cpython/
error: `ruff <path>` has been removed. Use `ruff check <path>` instead.
```
**Solution**: I added `check`.
## Test Plan
I tested it by running the benchmark-related commands in a new workspace
within GitHub Codespaces.
## Summary
This PR adds symbols and definitions introduced by `with` statements.
The symbols and definitions are introduced for each with item. The type
inference is updated to call the definition region type inference
instead.
## Test Plan
Add test case to check for symbol table and definitions.
## Summary
Provide instructions to use Ruff together with other servers in the Kate
editor.
Because Kate does not support running multiple servers for the same
language, one needs to use the ``python-lsp-server`` (pylsp) tool.

## Summary
This PR adds symbols introduced by `match` statements.
There are three patterns that introduces new symbols:
* `as` pattern
* Sequence pattern
* Mapping pattern
The recursive nature of the visitor makes sure that all symbols are
added.
## Test Plan
Add test case for all types of patterns that introduces a symbol.
## Summary
This PR adds definition for augmented assignment. This is similar to
annotated assignment in terms of implementation.
An augmented assignment should also record a use of the variable but
that's a TODO for now.
## Test Plan
Add test case to validate that a definition is added.
